Objective To investigate the efficacy and safety of endoscopic surgery in the treatment of elderly patients with lung cancer. Methods 90 elderly patients with lung cancer in our hospital were divided into two groups,45 cases in each group. The observation group was treated with thoracoscopic lung resection in 45 cases, the control group of 45 cases received conventional open lung cancer resection. The operation time, intraoperative blood loss, thoracic drainage time, lymph node dissection, postoperative hospital stay, pain score, pulmonary function assessment and postoperative complications were compared. Results There were no significant differences in the operation time and lymph node dissection between the two groups (P>0.05). The thoracic drainage time,intraoperative blood loss pain score and hospitalization time in the observation group were lower than those in the control group(P<0.05).The incidence of postoperative complications in the observation group was lower than that in the control group(P<0.05). The forced expiratory volume, forced vital capacity, vital capacity, one-second forced expiratory volume and forced vital capacity of the observation group were better than those in the control group after operation(P<0.05).

Objective To construct a gemcitabine-resistant variant of the breast cancer cell line (4T1/Gem) and establish a nude mouse model of breast cancer with hepatic metastatic. Methods A gemcitabine-resistant variant of the breast cancer 4T1 cell line was induced by gradually increasing the concentration of gemcitabine; this variant is referred to in this study as 4T1/Gem. The proliferation suppression rates of 4T1 and 4T1/Gem cells were determined by using the CCK-8 essay to evaluate the drug resistance indices of the cell lines. Western blot analysis was used to detect P-gp protein expression. Under ultrasonography, a 4T1/Gem cell suspension was injected into nude mice to induce liver tumors. H&E staining was used to observe tumor pathology, and immunohistochemistry was used to detect the expression of ER, PR, HER-2, Ki-67, and P-gp. Results After 14 months of induction, a 4T1/Gem cell line is established successfully. The cell line can grow stably in culture liquid containing 40 μg/ml gemcitabine. The drug resistance index of 4T1/Gem is 788.547. Compared with the 4T1 cell line, the 4T1/Gem cell line can upregulate P-gp protein expression and successfully establish a nude mouse model of breast cancer with hepatic metastatic. ER, PR, and HER-2 proteins exhibit negative expression in the tumor tissue. The positive expression of P-gp and 10% of Ki-67 proteins is also observed. Conclusion This study successfully constructs a gemcitabine-resistant variant of the breast cancer cell line (4T1/Gem)and establishes a nude mouse model of breast cancer with hepatic metastatic, thereby providing an experimental basis for developing and treating a drug-resistant variant of breast cancer.

Objective To compare the efficacy and safety of paclitaxel liposome combined with cisplatin and paclitaxel combined with cisplatin in the treatment of advanced non-small cell lung cancer (NSCLC). Methods 48 patients with advanced NSCLC were randomized into two groups, experimental group were given paclitaxel liposome at 175 mg/m²,and control group were given paclitaxel at 175 mg/m². Both groups combined with DDP at 75 mg/m² per cycle every 21 days.The efficacy and safety were evaluated after two cycles. Results The overall response rate was 37.50% in experimental group and 41.67% in control group, and the disease control rate was 79.17% in experimental group and 83.33% in control group. There was no significant difference between two groups(P>0.05). Though there was no significant difference in incidence of neutropenia,anemia, thrombocytopenia and alopecia, nausea and vomiting, but the occurred rates of rash、muscle pain and peripheral neuritis were significantly lower in experimental group than those in control group. Conclusion In the treatment of advanced NSCLC, both paclitaxel liposome combined with cisplatin and paclitaxel combined with cisplatin have similar efficacy, but paclitaxel liposome can significantly reduce the incidence of peripheral neuritis and serious hypersensitive reactions.

目的 研究超声内镜(EUS)对结直肠癌(CRC)术前分期和指导手术方案的应用价值。方法 选取我院2014年11月—2015年11月结直肠外科收治的52例CRC患者,均接受根治性切除术治疗并经术中病理观察确诊,并以手术病理TNM分期结果作为金标准。术前对入选患者行超声内镜检查,参考金标准回顾性分析超声内镜的TNM分期诊断效果。结果 该52例CRC患者EUS诊断结果显示肿瘤侵犯浸润T分期(T1～T4)准确率分别为87.50%、80.00%、94.12%、83.33%,较手术病理金标准无差异(P>0.05);EUS诊断淋巴结转移N分期(N0～N2)准确率分别为76.92%、79.17%、86.67%,其中N0、N2准确率较金标准无差异(P>0.05),但N1分期准确率较金标准偏低(P<0.05)。结论 虽然ENS对淋巴结转移程度尤其是N1的诊断准确度存在一定误差,但从整体来看EUS能较好的观察CRC患者肿瘤侵犯浸润深度和判断淋巴结转移情况,术前结合EUS诊断结果有利于患者术前病理分期,并为选择合适的手术方案提供参考依据。

Objective To study the application value of endoscopic ultrasonography (EUS) in preoperative staging of colorectal cancer (CRC) and guidance of surgical procedures. Methods 52 cases of patients with CRC who were admitted in the department of colorectal surgery of our hospital from November 2014 and November 2015 were selected. All of them underwent radical resection and were confirmed by surgical and pathological observation. Surgical and pathological TNM staging results were taken as golden standard. Before surgery, endoscopic ultrasonography was performed in the selected patients. Referring to the gold standard, TNM staging diagnostic effects of endoscopic ultrasonography were retrospectively analyzed. Results The EUS diagnostic results of 52 patients with CRC showed that the accuracy rates of tumor invasion T stage (T1-T4) were 87.50%, 80.00%, 94.12% and 83.33% respectively. There was no significant difference, compared with surgical and pathological golden standard (P>0.05); The accuracy rates of EUS in diagnosis of lymph node metastasis N stage (N0-N2) were 76.92%, 79.17% and 86.67%, respectively. There was no significant difference in accuracy rate in N0 and N2, compared with the gold standard (P>0.05), but the accuracy in N1 stage was lower than that of gold standard (P<0.05). Conclusion Although ENS has some errors in the diagnosis of degree of lymph node metastasis, especially N1, on the whole, EUS can be better to observe the depth of tumor invasion and lymph node metastasis in patients with CRC. The diagnosis combining with EUS before surgery is helpful to the preoperative pathological staging, and provide reference for the selection of appropriate surgical procedures.

Objective To study the effects of PF induced chemotherapy combined with intensity modulated radiation therapy and two-dimensional radiotherapy on the short and long term curative effects in nasopharyngeal carcinoma. Methods The treatment condition of 101 cases of patients with nasopharyngeal carcinoma who were treated in the Tumor Hospital Affiliated to San Yat-sen University between January and December 2008 were retrospectively analyzed. According to different treatments, the cases were divided into the intensity modulated group and the two-dimensional group. The clinical curative effects, short-term toxic and side effects and survival status were compared between the two groups. Results At the end of radiotherapy, the total remission rate in the intensity modulated group was 92.86% while in the two-dimensional group was 77.97% (P<0.05). In the intensity modulated group, the incidence rates of grade Ⅲ-Ⅳgastrointestinal tract reactions (26.19%) and mucositis (14.29%) were significantly lower than those in the two-dimensional group (P<0.05). There was no significant difference in long-term side effects and survival rate between the two groups (P>0.05). Conclusion PF induced chemotherapy combined with intensity modulated radiation therapy in the treatment of patients with nasopharyngeal carcinoma has good short and long-term curative effects and few toxic and side effects.
